What's that light "pinging" sound???

[Big-Foot]

I get it whenever the car is in motion - I can put my foot on the clutch and let the engine go to idle, put it under a heavy load (5th gear at 30) - no difference... Just a very light pinging type sound. I've pretty much ruled out detonation due to the fact that the sound is there regardless of load. I've turned off everything (including heater fan) .. Still there...

Anyone else have the same thing?

Probably won't matter after this weekend because I'll be installing the new Magnaflow exhaust - but I would still like to know whatintheheck it is/was!

A lot of people have found the inspection plate on the tranny to be loose (and missing 2 bolts, I think.) It usually rattles when the engine is cold and at idle, so it doesn't exactly match your symptoms; but I thought I would throw it out there.

Thanks Scro... I'll check it out when it's on jack-stands this weekend for his new exhaust system..

That explaination actually sounds plausible since there is no particular rhythm to the sound and the sound would be typical of an aluminum tag jingling against something..

I have a clicking sound after going to the 93 octane. It does not sound like a ping. It is only noticable when going WOT.

Looked around under there and didn't find anything...
